ideal gas

ideal gas

n.

A gas having particles that have perfectly elastic collisions and negligible volume and intermolecular forces, thus exactly obeying the ideal gas law. No known gas is an ideal gas, but actual gases approximate this behavior at relatively low pressure and high temperature.

ideal gas

n

(Chemistry) a hypothetical gas which obeys Boyle's law exactly at all temperatures and pressures, and which has internal energy that depends only upon the temperature. Measurements upon real gases are extrapolated to zero pressure to obtain results in agreement with theories relating to an ideal gas, esp in thermometry. Also called: perfect gas

i·de·al gas

(ī-dē′əl)

A gas in which there is no interaction between the individual molecules. Such a gas would obey the gas laws (such as Charles's law) exactly. No known gas qualifies as an ideal gas.

The initial air surrounding the conductor before its EE and the <<metallic plasma>> formed in place of the solid body of the conductor under study are assumed to be ideal gas media that satisfy the classical concept of an <<ideal gas>> with its limited volume [10].

Based on the density of water and the ideal gas law, it can be shown that a cubic meter of water holds about 1360 times more hydrogen than is contained in the same volume of pure hydrogen gas at standard temperature and pressure (STP), even though the volume of hydrogen depends on temperature and pressure.
